BEST MODE OF CARRYING OUT THE INVENTION

Referring now to drawings, a description will be made of an embodimentof the present invention.

STRUCTURE OF FIRST ELECTRONIC WATCH HAVING ORGANIC EL ELEMENT

FIG. 1 represents a sectional view of an electronic wrist watch to whichthe present invention is applied.

A case 11 of this electronic wrist watch is shaped as a ring, theupper/lower surfaces of which are opened. Inside this case 11, a circuitboard 12 is sandwiched by an upper housing 13A and a lower housing 13Bto be assembled as a module 15, under such a condition that a metalplate 13C is arranged on a lower surface of this lower housing 13B. Theupper housing 13A and the lower housing 13B are made of plate-likesynthetic resin. Under such a circumstance that this module 15 is fixedto the case 11 by a screw 14, a rear lid 16A is mounted via awater-proof packing 16B on the case 11.

Furthermore, a gear train mechanism 17 of a hands type watch and acrystal oscillating element 18 are assembled in the module 15. A drivecircuit (not shown) of the gear train mechanism 17, a drive circuit of aliquid crystal display apparatus (will be described later), and also adrive circuit of an EL light emitting apparatus are mounted on thecircuit board 12.

From the gear train mechanism 17, an hour hand shaft 19 and a minutehand shaft 20, which are rotatably driven, are coaxially provided. Thesehour hand shaft 19 and minute hand shaft 20 pass from a center throughhole 21 of a dial (face) apparatus 30 (will be discussed later) throughthe upper surface of this dial apparatus 30. Then, an hour hand 22 ismounted on the hour hand shaft 19, and a minute hand 23 is mounted onthe minute hand shaft 20 in such a manner that these hour hand 22 andminute hand 23 are rotated above the dial apparatus 30. A transparentglass body (watch glass) 24 is fitted into the upper opening of the case11 so as to close this upper opening. A ring-shaped partition plate 26is mounted between this glass body 24 and the outer peripheral portionof the dial apparatus 30, by which a rotation space 25 for the hour hand19 and the minute hand 20 is secured between this glass body 24 and thedial apparatus 30.

DETAILED STRUCTURE OF DIAL APPARATUS

The above-described dial apparatus 30 constructed of a light emittingapparatus is mounted on the upper surface of the module 15. This dialapparatus 30 comprises printed film 31 made by printing hour numerals ormarkers 31a on a transparent film using a fluorescent agent, an organicEL (electroluminescent) element 32 positioned behind this film 31, and asheet-shaped decoration plate 33 having a different color from theemission color of the organic EL element 32 positioned behind thisorganic EL element 32 along a light travel path. The organic EL element32 is electrically connected to the circuit board 12 by way of aninterconnector 28 arranged which penetrates through the upper housing13A.

The organic EL element 32 is characterized in that it becomestransparent when no voltage is applied, and emits the light when avoltage is applied. As indicated in FIG. 2, this EL element 32 ismanufactured by stacking, in an integral form, a surface transparentelectrode 32b, a hole transporting organic semiconductor+organicfluorescent pigment layer 32c, an electron transporting organicsemiconductor 32d, a back surface transparent electrode 32e, atransparent insulating coat 32f in this order. This surface transparentelectrode 32b is formed on an inner surface of a transparent substrate(PET, i.e., polyethylene terephthalate) 32a. Then, while using thesurface transparent electrode 32b as an anode and the back surfacetransparent electrode 32c as a cathode, when a DC voltage is appliedbetween both these transparent electrodes 32b and 32e, light is emittedfrom this organic EL element 32 with high intensity on the anode side,and low intensity on the cathode side. The decoration plate 33 is madeof, for example, a colored-plastic film sheet, on which such a patterncapable of giving high-grade quality and decorative feelings is printed.

FUNCTIONS OF FIRST DIAL APPARATUS

In the first dial apparatus with the above-described structure, sincethe decoration plate 33 is arranged behind the organic EL element 32which becomes transparent during the turn-OFF operation, the color andthe pattern of this decoration plate 33 can be observed in a see-throughmanner. When the light is emitted from the organic EL element 32, sincethe printed film 31 is located on this organic EL element 32, the hournumerals or markers 31a can be illuminated by the light emitted from theorganic EL element 32, and also both the hour hand 22 and the minutehand 23 can be illuminated. Accordingly, two different background colorscan be produced, so that a present time can be visually read even indark areas, and furthermore, the decorative features as well ashigh-grade feelings can be improved. When the fluorescent agent isemployed to print out the hour numerals or markers 31a, the afterglowcan occur in the hour numerals or markers 31a when the organic ELelement 32 is turned OFF, resulting in an improvement in terms of visualrecognition after turning-OFF of this organic EL element 32. It shouldbe noted that when the electrode of the organic EL element 32 is shapedas a character or a pictorial pattern, the electrode of the organic ELelement 32 may emit light having such a specific shape, resulting inbetter designs.

Alternatively, various characters, symbols, and pattern other than theabove-described hour numerals or markers 31a may be printed on theprinted film 31. Further, the hour numerals or markers 31a may bedirectly printed on the transparent substrate 32a of the organic ELelement 32, which may be used as the printed film 31.

OTHER EXAMPLES OF DIAL APPARATUS 30

FIG. 3 schematically shows another example of a dial apparatus 30B.

In this dial apparatus 30B, the printed film 31 is sandwiched betweenthe organic EL element 32 and the decoration plate 33. As a consequence,when the organic EL element 32 is turned OFF, namely when noillumination is required because of use in a light environment, the hournumerals or markers on this printed film 31 can be observed through thetransparent organic EL element 32. When the organic EL element 32 isturned ON in a dark environment, the hour hand 22 and the minute hand 23can be observed since the light is emitted from this organic EL element32, so that a present time instant can be read. The illumination effectby the organic EL element 32 of this example may be increased, ascompared with that of the organic EL element 32 shown in FIG. 1. As aresult, this dial apparatus 30B may be utilized, for instance, as aflash light for illuminating surrounding areas.

FIG. 4 represents an electronic wrist watch according to anotherembodiment of the present invention. It should be noted that the samereference numerals shown in FIG. 1 are employed as those for denotingthe same or similar structures of FIG. 4, and explanations thereof areomitted.

In accordance with this embodiment, a semi-transparent reflection plate34 is arranged above hands (namely, hour hand 22 and minute hand 23),and a transmission type liquid crystal display (LCD) apparatus 35 isarranged over this semi-transparent reflection plate 34. The liquidcrystal display apparatus 35 is capable of displaying time and varioussorts of data in a digital form. The information displayed on thisliquid crystal display apparatus 35 is readable by utilizing thereflection light derived from the semi-transparent reflection plate 34.In such a case that no information display is made, or a small amount ofinformation display is made, the hour/minute hands 22, 23, and the dialapparatus 30 may also be read. In this case, the color of this dialapparatus 30 is equal to the color of the decoration plate 33. When thedial apparatus 30 is driven to emit the light in night time, the colorof the dial apparatus 30 becomes the color of the organic EL element 32,so that the hour hand 22 and the minute hand 23 can be visually read.Alternatively, both the semi-transparent reflection plate 34 and theliquid crystal display apparatus 35 may be arranged under thehour/minute hands 22/23, and further about the dial apparatus 30.

FIG. 5 schematically indicates another embodiment of the presentinvention.

In accordance with this embodiment, the position of the semi-transparentreflection plate 34 indicated in FIG. 4 is changed. That is, a dialapparatus 30C is constituted by containing the semi-transparentreflection plate 34 which is arranged between the printed film 31 andthe organic EL element 32. When the semi-transparent reflection plate 34is arranged in this manner, the printed film 31 can be illuminated bythe reflection light from the semi-transparent reflection plate 34 whilethe organic EL element 32 is turned OFF, whereas this printed film 31can be illuminated by the light emitted from the organic EL element 32while this organic EL element 32 is turned ON. As a consequence, thevisual recognition of the hour numerals/chapters can be further improvedin any of the reflection light/emission light.

FIG. 6 schematically shows a dial apparatus 30D according to a furtherembodiment of the present invention.

In this dial apparatus 30D, a solar cell 33B is employed instead of thedecoration plate 33 used in the first embodiment. The solar cell 33B iselectrically connected to the circuit board by way of an interconnector27. When this decoration plate 33 is substituted by the solar cell 33B,the background color of the organic EL element 32 during the OFF-stateis equal to the color of this solar cell 33B. Also, since externallysupplied light can reach the solar cell 33B when the organic EL element32 is turned OFF, this solar cell 33B can generate electric energy, sothat this generated electronic power can drive the electronic wristwatch.

It should also be noted that a solar cell may be employed in any of theabove-described embodiments, instead of the decoration plates.Alternatively, as modifications related to the first and thirdembodiments, but the back face electrode (cathode) of the organic ELelement 32 is made of a metal electrode. Then, this metal electrode mayfunction as the decoration plate. In this modification case, the colorof the metal electrode constitutes the background color when the organicEL element 32 is turned OFF.

While the light emitting apparatuses 30, 30B, 30C, and 30D have beenapplied to the respective electronic wrist watches in the respectiveembodiments, the present invention is not limited thereto, but may besimilarly applied to many other electric appliances.

Moreover, instead of the above-explained organic EL element 32, anyother light emitting elements which emit light in the drive mode andbecome transparent in the non-drive mode may be similarly utilized.

DETAILED STRUCTURE FOR MOUNTING DIAL APPARATUS

FIG. 7 to FIG. 11 represent another embodiment of the present invention,namely, indicate a mounting structure of a dial apparatus in detail. Inthe drawings, reference numeral 50 denotes a watch module (drive unit)for storing therein a circuit board, a crystal oscillating element, agear train mechanism of an analog watch, and the like.

On an upper surface of this watch module 50, a disk-shaped transparentorganic EL element 51 and a dial (face) 52 are mounted in a stackingmanner. In this case, the dial 52 is a disk-shaped transparent memberhaving a surface on which hour numerals or markers 53 are printed. Asindicated in FIG. 9, a center portion of this disk-shaped transparentdial 52 is curved along the rear surface direction to form a convexshape. A dial depressing member 54 is mounted on an outer peripheralportion of the watch module 51 so as to constitute the EL element 51 andthe dial 52 in an integral form with this watch module 50.

This dial depressing member 54 is a ring-shaped member made of syntheticresin, and is mounted on an outer peripheral portion of the watch module50 in such a manner that this outer peripheral portion of the watchmodule 50 is engaged with an inner peripheral groove 55. An upper hookportion 56 for hooking the EL element 51 and the peripheral portion ofthe dial 52 is formed on an upper edge portion of this dial depressingmember 54. In this case, as shown in FIG. 10, the dial depressing member54 is manufactured in such a manner that a height "B" defined from theupper edge portion of this inner peripheral groove 55, namely the uppersurface position of the watch module 50 up to the upper hook portion 56becomes slightly larger than a summation between a thickness of the ELelement 51 and a thickness of the dial 52.

The watch module 51 in which the EL element 51 and the dial 52 are madein an integral form by the dial depressing member 54 in theabove-described manner is constructed as a unit on which a hour hand57A, a minute hand 57B, and a second hand 58 are mounted, as illustratedin FIG. 7 and FIG. 8. As shown in FIG. 11, this watch module 50 isassembled within a case 59 of an electronic wrist watch through a rearsurface opening of this case 59. Furthermore, this rear surface openingof the case 59 is closed by a back plate 60.

According to the mounting structure of the dial 52 made of theabove-described structure, the following merit can be achieved. That is,the outer peripheral portion of the watch module 50 is engaged with theinner peripheral groove 55 of the dial depressing member 54.Furthermore, the dial depressing member 52 is fabricated in such a waythat the height "B" defined from the upper surface position of the watchmodule 50 up to the upper hook portion 56 for hooking the EL element 51and the peripheral portion of the dial 52 becomes larger than thesummation between the thickness of the EL element 51 and the thicknessof the dial 52. As indicated in FIG. 11, when these members areassembled in the case 59, even when the depressing force is exerted fromthe watch module 50 to the dial depressing member 54, this depressingforce is not given to the EL element 51. As a consequence, there is nosuch a risk that the EL element 51 having flexibility is conventionallydeformed, and therefore the center portion of the dial 52 is floatedupwardly.

In addition, as indicated in FIG. 9, since the center portion of thisdial 52 is curved toward the EL element 51 in a convex shape, even whenthe above-defined height "B" is made larger than the summation betweenthe thickness of the EL element 51 and the thickness of the dial 52, aspace produced between both members can be absorbed by the curved dial.As a consequence, it is possible to avoid a play produced between thesemembers.

On the other hand, FIG. 12 to FIG. 19 indicate a further embodimentaccording to the present invention.

As shown in FIG. 12 to FIG. 14, a disk-shaped dial 63 according to thisembodiment is mounted as follows. That is, a transparent organic ELelement 62 having a surface on which hour numerals/chapters (not shownin detail) is formed is adhered to a thin-metal plate 61 with a higherstrength such as SUS631 by employing acrylic ad-hesive agent and thelike to thereby form an integral form. A pattern and the like are coatedon a surface of this thin-metal plate 61. Tongue-shaped portions 66 and66 projected along the diameter direction respectively are formed at a3:00-position and a 9:00-position opposite to the diameter direction ofthe metal plate 61. Then, the watch module 64 and the dial plate 63 areassembled in an integral body by a frame member 65 in this electronicwrist watch, as illustrated in FIG. 15 to FIG. 19.

This frame member 65 is a member made of synthetic resin by combining aring-shaped bottom plate 67 with an upper edge portion (peripheral edgeportion of opening) 68 by using a plurality of pillars 69 to therebyform an integral body. A height of the pillar 69 is made substantiallyequal to a thickness of the watch module 64. Hook portions 70 are formedon the upper edge portion 68 at plural positions thereof along thecircumferential direction, and the outer peripheral portion of the dial63 is engaged with these hook portions 70. Stepped portions 71 areformed among these hook portions 70 and projected from the upper edgeportion 68 so as to engage the outer peripheral portion of the dial 63.Grooves 72 and 73 engageable with the tongue portions 66 of the metalplate 61 are formed at a 3:00-position and a 9:00-position of this upperedge portion 68. Furthermore, an outer dimension of this frame member 65is designed so as to be closely fitted to a casing 73 into which thisframe member 65 is assembled.

Then, the watch module 64 is mounted on the bottom plate 67 of thisframe member 65. The dial 63 is mounted on this watch module 64 in sucha manner that the tongue portions 66 thereof are positioned into thegrooves 72. Also, the outer peripheral portion of the dial 63 is engagedwith the hook portions 70. As a result, the movement of the dial 63along the upper/lower directions is blocked by the hook portions 70.Also, the movement of this dial 63 along the radial direction is blockedby the stepped portion 73. Furthermore, this dial 63 is mounted on theframe member 65 under such a condition that the movement thereof alongthe circumferential direction is blocked by the grooves 72.

As represented in FIG. 19, both the watch module 64 and the dial 63which are assembled by the-frame member 65 in an integral form in thismanner are assembled into the casing 73 of this electronic watch.

As previously described, with respect to the mounting structure of thedial, the dial 63 to which the metal plate 61 and the EL element 62 areadhered in an integral form is fixed in such a manner that the tongueportions 66 are fitted into the grooves 72 of the frame member, andfurther the outer peripheral portion thereof is engaged with the hookportion 70. Accordingly, the movement of this dial 63 along theplate-thickness direction is blocked by the hook portions, and themovement thereof along the plate-surface direction is blocked by thestepped portions 71. Also, the rotational movement of this dial 63 alongthe circumferential direction is blocked by the grooves 72. As aconsequence, a mounting leg such as that used in the prior art is nolonger required to join the dial, so that such a metal material havinghigh strength, for instance, a stainless steel can be selected as themetal plate 61, and further this dial 63 can be firmly fixed on theframe member 65.

Moreover, since the outer dimension of the frame member 65 is set so asto be closely fitted to the casing 73 into which this frame member isassembled, it is possible to avoid a play produced between the dial 63and the watch module 64 within the casing 73.

It should be noted that the dial mounting structures of the embodimentsof the present invention have been applied to those of the analog watchand the pocket watch. However, the present invention is not limited tothese applications, but may be applied to other dial mounting structuresin electronic appliances.

Also, the light emitting element is not limited to the above-describedEL element, but may be similarly applied to various sorts of lightemitting elements mounted on the above-described drive unit with thedial in a stacked layer.
